WM-CLC1, 30mx0.32mmx1.8µm

The WM-CLC1 GC capillary column 30mx0.32mm, 1.8µm, is an application-specific specialised column and is offered in a single configuration with a thick film of 1.8 µm. Composition, polarity and USP phase group are not published for this designation, and the abbreviation CLC is not expanded. The thick film indicates a design for highly volatile components that would elute too early on thinly coated columns. WM-CLC1 is used particularly where standard phases do not provide sufficient selectivity for demanding multicomponent mixtures.

Features and Benefits

• High-performance columns with low bleed
• Standard, MS, HT, and specialty phases
• Nonpolar to highly polar
• WCOT and PLOT versions
• Individual performance testing for each column

Additional Information

The WM series is the high-performance line of the gas chromatography product portfolio and covers demanding routine, GC-MS, and specialty applications. The MS variants feature the same phase chemistry as their respective base phases but are manufactured to stricter specifications, with dedicated surface deactivation and a lower desorption rate. In addition to the classic polysiloxane and wax phases, the series includes application-specific columns tailored to a single analytical method. In PLOT columns, adsorption strength and carrier gas velocity determine the separation, and water in the carrier gas shifts the retention.
